Hi Tony & Philip Hihi. If it wasn't for all you guys finding bugs, ordering kits and requesting enhancements, Mrs UPL would have somewhat less to complain about too ;-) I remember those too, and I

It was nearly 55 years ago I built my first crystal radio set. I was four or five at the time and had discovered a wonderful book in the local library. I had sneaked into the adult section and

LOL = I made my first crystal set when I was eleven. I did it on my bedroom floor, but first it took me weeks to buy the parts. The most expensive bit was the brown 500pf variable with brass vanes. I

Fun times though Tony... Strange to think that nearly sixty years ago I was sat at the table making crystal sets and stuff and here I am, still doing it! I blame Hans.. If it wasn't for him, I would

but do you remember how the frequency ran away when you went anywhere near the thing Philip? I had some kits marketed under the name 'HAC' - Hear All Continents. And you're right, they were

Tell you what Tony, those Denco coils were expensive... A lot of my pocket money went towards buying a couple when I was a lad. Loved the idea of them coming in screen cans and that folded up

Is that a 'Denco' filter? :)) Do you remember the Denco plug in coils? long ago, I had a regenerative receiver kit that handled band changes just like that. They were really terrible things, they

Done a mod today to make use of Hans pluggable LP filters... Mounted the filter sockets on some PCB on the lid of the case. These are coax wired internally and I can just swap out filters without

I love the way you build things Philip. That stuff looks great. G0bzb Tony

Received my second kit this morning....thanks Hans I had a box ready prepared for it. This large box is designed so I can tinker with things like filters power supplies and PA stages hence the roomy

Hi Keith Yes, it will! 73 Hans G0UPL

Good morning Hans (and all), I am still working towards getting my U2 kit built and on the air and I have been taking note of the discussions around GPS and new versions of firmware. At the moment

Well done Hans.... Will be nice to get my Trimble unit working again... Great stuff Philip G4JVF

Woooop di do!! bzb

I can see it now... Ultimate 3 including a real time clock like this one... Tell the new U3 your 10 character grid and watch it keep the transmitter on

That's great news Hans. I solved the problem with my Up501 gps by adding ferrite beads on every lead connected to the gps. It would seem that gps modules do not like being close to rf fields. It

Yey, that will be fun.I shall mug every passing Postman for the next few days.:-) Indeed that would be excellent progress, I do hope that widespread compatibility is achieved. 73 Eddie G3ZJO

Sounds very good to me. Will this still be happy with the Adafruit unit and the 100mS pulse width? 73 Keith.

All As some of you know, I have what I call a "GPS Simulator" which is an ATmega88 I programmed to send a NMEA string with the $GPRMC sentence, and it also has a realtime clock which updates

Today I took delivery of 2.02k and some extra LPF boards. Along with my Adafruit GPS, it's working very well. I've been running WSPR and FSKCW on 30m within the same ten minute frame for a few
